21cc...

 

My compression is off according to a $40 Napa gauge.... I need a second opinion.

 

Otherwise, I need a rebuild ASAP.

comp. ????

 

Before the build it was around 100 psi each cylinder... not sure what it is right now.

 

(I know I should have checked it already.)

Can't remember did you redo the topend or you talkin about the mods you just done? Thats pretty low, with the new domes you should be about 120-125 going off what you already had. You should actually be at about 150-155, do you have a guage to check?

I dont think you'll hear a ping from detonation over the noise of the

pipes.

About the only singn of detonation (prior to blowing a hole in the piston)

is the plugs backing out.

Keep a close eye on how the plugs burn.

Do a plug chop to be sure

I can't check it until I get the bike back...it's out at my parents house, gettin it Thurs.

 

I'll check it then and get back to you.

 

Thanks all.
